A high-fiber diet has a lot of health benefits. It can help lower cholesterol and control blood sugar. And it can help you maintain a healthy weight. Good sources of fiber include beans and peas, fruits and veggies, and whole grains, like oats and whole wheat products. You could have a piece of whole wheat toast for breakfast and an apple for a snack. Or enjoy black beans for lunch and steamed green beans for dinner. Eating a variety of fiber-rich foods can help you get the recommended amount of fiber in your daily diet.
